MACHINE FOR UNITING LOOPED FABRICS.

SPECIFICATION forming part of Letters Patent No. 584,224, dated J' une8, 1897. Application filed September ,22, 1894. Renewed March 29,1897.Serial No. 631,315. (No model.)

To @ZZ whom it may concern,.-

IBe it known that l, SAMUEL HENSHALL, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Machines for Uniting Looped Fabrics, ot' which thefollowing is a specification.

My invention relates to a machine of the same class as that forming thesubject of my application iiled March 27, 189i, Serial No. 505,311-thatis to say, a machine in which one set of sewing mechanism is combinedwith a series of work-carrying heads movable in respect to said sewingmechanism, so that they may be successively brought into operativerelation. thereto, the objects of my present invention being to providefor the desired adjustment of the work-carrying heads in respect to thesewing mechanism without the necessity of throwinginto and out of actionon each adjustment the mechanism whereby the intermittent movements areimparted to each of said Work-carrying heads and to render unnecessarythe duplication of the feeding' devices, asin the former machin e. Theseobjects I attain in the manner hereinafter set forth, reference beinghad to the accompanying drawings, in Which- Figure l is a plan View of amachine'constructed in accordance with my invention.

.Fig 2 is a transverse section, on an enlarged scale, of that part ofthe machine to which my present invention relates; and Fig. 3 is atransverse section illustrating a modiiication of the invention.

In Fig. l, A represents a bed-plate upon which is mounted any ordinaryform of sewing mechanism such as is employed in machines for unitinglooped fabrics, said sewing mechanism usually comprising a vibratingneedle and a looper acting in conjunction therewith to form achain-stitch- As the sewing mechanism forms no essential part of myinvention, however, detailed description of the same will be unnecessaryexcept so far as to say that it comprises also mechanism forreciprocating a pawl a., which engages with a ratchet-wheel h, wherebythe work-carrying heads are rotated by a succession of intermittentmovements.

In Fig. l I have shown the machine as provided With a series of threeWork-carrying cylinders d, and my present invention comprises themechanism for effecting the rotation of these cylinders in such mannerthat they can be successively brought into operative relation to thesewing mechanism without necessitating any du plicating` or throwing outof action of the devices for effecting such rotation.

Each of the cylindrical heads d is mounted in a tubular boss f, formedupon a plate g, which is mounted so as to be free to turn in a tube h,secured to or forming part of the bed-plate A of the machine, said tubealso having formed thereon, by preference, a bearing h for the shaft t',which carries a ratchet Wheel b of the rotating device.

Each work-carrier d has at the upper end the usual vertically-projectingstitch-receiving points m, Which are secured in place upon the cylinderby an outer sectional ring m', and to the lower end of each of thecylindrical Work-carriers is secured a toothed ring n, the teeth ofwhich engage with those formed upon the top of the duplex annular rackp, which is also mounted in the tube 7i, so as to be free to turntherein.

The teeth formed upon the bottom of the duplex annular rack p mesh withthose of the bevel-Wheel s upon the shaft i, so that when said shaft isrotated rotating movement will be imparted to the duplex rack p andthence to each of the cylindrical work-carriers d.

The intermittent movement of those workcarriers which are not inoperative relation to the sewing` mechanism is not so rapid as tointerfere With the ready application of the new work thereto by theattendant. In fact, the automatic rotation of these inoperative heads israther an aid to the application ot the Work thereto.

During the looping operation the plate g is locked to the tube 7i. bymeans of a pin t, engaging with openings in said tube and in thedownwardly-projecting flange g' of the plate; but When the loopingoperation has been completed in connection with the knitted tubescarried by one of the cylinders d the pin t is Withdrawn and the plategis turned by hand so as to bring another of the said cylinders intooperativerelation to the sewing mechan- ICO ism, the pin being` thenreinsertedso as to again lock the plate g.

The movement of the plate g is preferably such as to carry the cylindersd past the sewing mechanism from 'left to right, so that the rack p willtravel with the plate and cause forward movement to be imparted to thebevel-Wheel s, thereby causing the teethy of the ratchet-Wheel l) totravel forward under the pawl a, although this is not absolutelyessential, the objection to moving the'plate in the opposite directionbeing that the rack p cannot in this `case move with it. Hence thework-carriers will be rotated in the plate as it is moved, whereas whenthe plate is moved yinr the ydirection iirst referred to thework-carriers do not turn around their own axes during the movement ofthe plate g.

Although Iy preferthe use of the duplex rack p as a means oftransmitting the movementof the shafti to the work-holders, other fmeans within the scope of the main featurey of my invention may beadopted. For instance, in Fig 3 I have shown a construction in which acentral vertical bolt w, carried by the plate g, constitutes a bearingfor a sleeve w', which is gea-red by a bevel-wheel w2 to the bevel-wheels of the shaft fi, the upper portion of said sleeve w having aspur-pinion w3, which meshes with spur-wheels n on the cylinders cl.

rlhe plate g is vertically confined to the t-ube h by means of a ring ydetachably ysecured to the top of said tube, the removal of this ringpemittin g the release of the plate g from the tu e.

HavingV thus described my invention, kI claim and desire to secure byLetters Patentl. The combination in a machine for unitinglooped fabrics,of the sewing mechanism, thel plate carrying a series of work-holdingcylinders and movable so as to bring said cylinders successively intooperative relation to the sewing mechanism, means for holding the platestationary, a shaft occupying a fixed relation to said sewing mechanism,means for transmitting the movement of said shafty to the cylinders onthe movable plate, and means for rotating the shaft by a succession ofintermittent movements, substantially as speciiied.

2. The combination in a machine for uniting looped fabrics, of thesewing mechanism, the plate carrying ra series of work-holdingcylinders, and movableso as to bring said cylinders successively intooperative yrelation to the sewing mechanism, means for holding the platestationary, a shaft occupying a fixed relation to the sewing mechanism,means for rotating said shaft by a succession of intermittent movements,and gearing having as one of its elements a duplex annular rack wherebythe movement of saidfshaft is transmitted to the worlrholding cylinders,substantially as specified.

3. The combination in a machine for uniting looped fabrics, of thesewing mechanism, a plate carrying a series of work-holdin g cylinders,and movable so as to bring said cylinders successively into operativerelation to said sewing mechanism, a fixed frame, a cylinder-operating,shaft adapted to bearings thereon, means for locking the movable plateto and releasing it from said xed frame, means for imparting rotarymovement to the cylinder-operatin g shaft by a succession of inftermittent movements, and gearing whereby the motion of said shaft istransmitted to the i work-holders, substantially as specified.

4f. The combination, in a machine for uniting looped fabrics, of thesewing mechanism, a fixed tubular frame, a plate carrying a seriesofwork-holding cylinders and rotatable in said tubular frame so as tobring said cylinders successively into operative relation to the sewingmechanism, means for locking the said plate to and releasing it from the.fixed frame, a cylinder-operating shaft adapted to a bearing on thefixed frame, means for imparting rotary motionto said shaft by asuccession of intermittent movements, gear wheels upon the shaftandcylinders, and a duplex rack rotatable in the fixed tubular frame,and serving to transmit the movement ofthe shaft to A.the cylinders,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

SAMUEL HENSIIALL.
